Wiring Routing at the Transmission

[JOP33]

How are most builders handling wire(s) and routing at the Transmission area? Is it common practice to just have wires resting (or crossing) over the transmission underneath the fiberglass tunnel? How extensive does the heat protection need to be in this area, if so? Ideally, I would like to have all of my wiring be above the trans tunnel, but with the EFI, AC/Heater, Radio, Wipers,Gauges, etc., I just don't know that I can get there. I'd really like some additional input on this as I know most don't like to post pictures of their wiring. I have already made two passes with the wire cutters and soldering iron and I am still "stuffy" in the area and I am concerned about routing it across the top of the trans (secured), but essentially running on the top of it and to the sides.

Thanks ahead of time.
